Filed: 1991-01-11
Abstract: PURPOSE: To provide a self aligning type contact and an interconnecting structural body for attaining the further high density of an MOS transistor used for a CMOS integrated circuit, and a method for manufacturing it. CONSTITUTION: A self aligning type source and drain contact 5 is overlapped on a gate 6, and the formation of a short circuit with the gate 6 is prevented by oxide separation between the source/drain contact 5 and the gate 6 and a silicon nitride layer on the gate 6. A contact 7 to the gate 6 is formed on the gate 6 at the upper part of the active area of a transistor. The gate contact 7 is exposed in the source and drain area, and it is protected by a photoresist layer hardened in the etching period of an insulating layer. The source, drain and gate contacts 5 and 7 are protected by a titanium silicide layer, and therefore it is pot necessary for an interconnector to completely coat those areas. A low resistance interconnector is formed of a titanium silicide surrounded by the thin film of titanium nitride.

Abstract: PURPOSE:To obtain a titled circuit which can operate under low voltages and is suitable for converting it to integrated circuits, by controlling the electric current in such a way that the potential difference across both ends of a resistance is equal to the offset voltage of a differentially amplifying circuit which is generated because of the difference in current density.

In the constant-current circuit, the difference in current density is produced by changing the emitter area of the transistors Q1, Q2. Moreover, the difference between the DELTAVBE and the R11XIREF turns back through a current mirror circuit composed of NPN type transistors Q6, Q7 and another current mirror circuit composed of PNP type transistors Q4, Q5, and performs compensation of the beta of the NPN and PNP types transistors consisting two constant-current sources.

Title: Method and apparatus for pickup in graphic system
Inventor: JIYON JIYOZEFU ROORESU
IPC: G06T11/80
Filed: 1992-03-24
Abstract: PURPOSE: To decide a primitive visible in a pick frame by eliminating hidden lines/hidden surfaces by using a Z buffer so that only the identifier of the primitive visible in the pick frame can be left while being stored. CONSTITUTION: A graphics control processor writes the pick index of a visible primitive in a pick frame in a pick frame 216 in a background frame buffer 210 by referring to a Z buffer. A value stored in the pick frame 216 is the pick index of primitives 301-303 and 305 actually visible in the pick frame. A primitive 304 crosses the pick frame 216, and is hidden behind the primitives 301-305. Therefore, the pick index of the primitive 304 is not written in the frame buffer. Then, all the picked primitives are re-plotted by using the pick index instead of a color value, and afterwards a synchronization command is transmitted to a shading processor.
